Process engineers strive to recover as much energy as is practically possible from the available process and utility streams within the constraint of the plant. To achieve this goal, traditional—and sometimes non-traditional—methods are utilized. In a steam cracker, light olefins are considered the highest-value products, and utilizing “cold energy,” or refrigeration, is the primary means to recover these products. Refrigeration has proven to be a relatively expensive form of energy, and minimization of refrigeration usage in the processing scheme leads to lower operating costs, thereby improving profitability. The pursuit of this goal has led to novel design approaches in combining process
